that rhodium, osmium, selenium, &c, are to be found, and 
he will take pleasure in showing you these and other speci- 
mens. Berzelius is constantly occupied. He works from 
twelve to fourteen hours daily ; but, notwithstanding all he 
has done for experimental chemistry, it must not be sup- 
posed that he works unceasingly in his laboratory. Fre- 
quently when composing, he ceases to work in the labora- 
tory for months together. If, while writing, as in the 
preparation of the last edition of his work on Chemistry, 
he meets with any passage that appears obscure, he quits 
his pen, and establishes himself in his laboratory, which he 
does not quit until he has obtained the desired result. He 
then returns to his editorial labors. 
His apartments are admirably arranged, so as to admit 
of his passing from his study into his laboratory. It is in 
his study that he receives his morning visitors. By the 
side of this apartment is a long room, in which his appara- 
tus is arranged ready for use, so that he can commence 
any operation without loss of time. It is thus that he has 
been enabled to lay out his time and make it of double 
value. — Pharmaceutical Journal, October, 1849, from

ART. XIV. — STERLING'S PROCESS OF MAKING AMBER 
VARNISH. 
In manufacturing amber varnish according to Mr. Ster- 
ling's method, the amber (which has to be submitted to high 
temperature to melt it) is introduced into a stout copper 
vessel, which is closed at top and luted with clay. This 
vessel is furnished at its lower end with a funnel-shaped 
vent, which carries a perforated sheet of iron or seive, suf- 
ficiently fine to prevent the escape with the melted amber 
of any impurities which might be contained in the amber.
